When Arithmetic is run with only one image and no operators it crashes. This is because of the behavior we have defined for efficiency: an image is only actually read into memory when it is ready to be operated on by an operator, not when it is confronted. In this way, when processing a large number of files, at any moment only the ones that are actually being operated on are in memory.

So when there is no operator, the contents of the image are not read into memory and we get a segmentation fault. I am now working on a solution to this problem.

Cases like this (when there is only one file operand and no operator) can happen in scripts.
